As to the boot parameter to enable this function, you suggested using
reset_devices. I found that on a certain platform resetting devices
caused PCIe error due to a hardware bug. Therefore I think we need
new parameter apart from reset_devices to disable this function on
such a machine.

Wouldn't a DMI quirk be better for this? That way the second kernel
internally would know not to do this.

That sounds good. I'll try it, thanks.

Thanks,
